Flexible Duct is widely used in Heating, Ventilation and Air Conditioning (HVAC) systems for air ventilation applications. Flexible Duct provides greater thermal efficiency to save energy. The product is also covered in a heavy duty, silver jacket for durability. The vapor barrier prevents condensation forming on the outside of ducts carrying air. Because it is flexible, it is easy to run around and through obstacles in the building.

Q:HVAC Heating: What are the main components of the air distribution system?

Geothermal construction, the heating pipe spacing can not be less than 100mm, the construction can not be achieved, big brother!

Q:External wall insulation method of operation There are several combinations of materials

30-150 per square meter has, mainly to see the material, thickness and so on

Q:Air conditioning machine work when the sound is too much reason

This is based on the density of benzene board decision, not what you said, know it buddy.

Q:Air to water heater host and air conditioning host is not the same

This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.

Q:Space blowing wind is not cold how is it?

Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High

Q:The installation method of ordinary air conditioner. The more detailed the better. Please thank you all

The basic operation of the same, but the different requirements of different professional, or to determine the direction of good, and then hands.

Q:Air conditioning ventilation when the sound is a big reason

No matter, it is best to cut the distance between the material and the roof, like an arbor. Otherwise it is not foam board with it

Q:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?

Decoration refers to the home improvement part, housing construction is the content of the building

Q:Single cold air conditioning function can not change the cold and warm?

So good, then you recommend more. Give an address. You are not layman, too modest.

Q:Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter

Not the ,,, mobile air conditioning inside the compressor, the winter heating also need the compressor, but also a ventilation pipe, charged heating Well?
